Offers that look like part of your store
Happy Bundle adds volume discounts, product bundles, buy X get Y and add-on offers to your Shopify product pages. They use your theme's fonts and colors, and Shopify applies the discount at checkout.

See every offer on a real store
Our demo store runs Happy Bundle on Horizon, Shopify's own theme. Each product shows one feature: quantity breaks in three layouts, bundles, mix and match, buy X get Y with a free gift, add-ons, countdown timers and badge styles. Choose an offer and add it to the cart, as a shopper would.
Shopify asks for the password because the demo is a development store. The demo is in all 12 languages of this site, and this link opens it in yours.
